IMPROVEMENT IN TIME GAS LIGHTING AND. EXTINGUISHING APPARATUS.

Specification forming P of Letters Patent 97,403, dated November 20,1877 application filed January 4, 1877. g

To all whom it may concern:

Be it known that we, TITUS Pownns and J nnorrn B. HULBERT, of the city,county, and State of New York, have invented an Improvement in Time GasLighting and Extinguishing I Apparatus, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

Figure 1 is a side elevation of an apparatus containing my improvements.Fig. 2 is an elevation of the opposite side of the same. Fig. 3 is aside view of the interior movements of the apparatus, the side plateseen in Fig. 1, with the works on the exterior face of the said plate,being removed. Fig. 4 is a plan of the same. Figs. 5 and 6 are detailedviews of some of the working parts hereinafter particularly described.

The object of this apparatus is to automatically turn on and oif the.gas, especially of the burners of street-lamps; and consists in thedevices and combinations of devices herein described and claimed.

We employ a train of clock-work, which is shown in the right-hand partof Fig. 3, and which, being common and well known, need not beparticularly described. The object of this train of clock-work is togive a uniform rotation, once in twenty-four 7 hours, to the wheel 0,and it is constructed and arranged to accomplish that result.

At the opposite end of the frame is another train of wheels, D E d themotive power being the recoil of a coiled spring acting upon the shaft dof wheel D. The object of this train of wheels is to give to thecrankarm 6 on the shaft 0 of the wheel E, an intermittent movement, ahalf-revolution twice every twenty-four hours. The wheel D and pinion dmade fast to it, are both loose on' the shaft d, and motion is given tothem-by means of a ratchet-wheel, D, fixed to said shaft, and a dog, a,pivoted to the wheel I), and engaging with the said ratchet-wheel. Thisarrangement permits the spring S to be woimd up without moving the wheelD. d is a stop-pin on the side face of thewheel D near its periphery.

F is a bell-crank lever, pivoted at f in plate B. On the inner face ofthe endd of said lever are two projections, sections of which (marked dand d) are shown in Fig. 3, which extend through an opening in theplateB, and

nearly into contact with side face of wheel D.-

swinging the end d of the said lever upward and to the left, and, ofcourse, depressing the opposite end d; but if the end 01 of thesaidlever is prevented from being depressed at the time the pin (1 fallsinto the slot 01 it will be stopped against the incline d, and cannotpass through the slot (1 until the end d of the lever is allowed tofall. As soon as the pin d passes through the said slot, the wheel D isfree to make a revolution, when the said pin will be again stopped uponthe projection d as the movement given to the lever by the passing ofthe pin 01 over the incline (1 will bring said projection into positionto engage said pin.

H is a sliding bar hinged at one end to the arm H, which is pivoted atits lower end, at c, in the plate B. c is a slotted opening in theopposite end of this bar, and c is a pin fixed in plate B, which passesloosely throughthis opening.

I On the shaft of the wheel 0, and between that wheel and the plate B,is a friction-wheel, a detached view of the same being given in Fig.- 6,and there indicated by the letter I. It is indicated, also, by dottedlines seen in the wheel 0, Fig. 5. It may be attached to or form a partof the wheel 0, its diameter being alittle less than said wheel.

The under edge of the bar H rests on the periphery of the said wheel I.A finger or pin, h, projects inward from the end 01 of le-' ver F, andrests upon the upper edge of the bar H. The action of the pin d pressingagainst the projections 01 d, is to depress the end (1 of lever F, and,of course, to force the finger it down upon the bar H. This bar,therefore, operates to hold the said lever in position to cause theprojections 01 d toengage the pin 0?. The surface 1 to 2 of the upperedge of the bar H is elevated above that down onto the lower surface 2to 3 of the bar from 2 to 3. When the finger h rests on the latter theprojection d engages with the pin d When it is raised onto the latterthesurface 1 to 2the said pin passes off from the said projection into theslots d Then, when the said finger is allowed to drop again onto thesurface 2 to 3, the pin passes through the said slot, and the wheel Dmakes a revolution.

z'and t" are two pinsfixed in the wheel 0. They are so placed that theyengage with the end d of lever F, and elevate it, as the said wheel isrevolved from left to right. The normal position of the finger hisresting on the lower surface 2 to 3 of the bar H. When the end d of thelever is raised by one of the pins the barH is slid to the left by thestress of the spring f against the arm H', when the finger will rest onthe surface 1 to 2 of the bar, pressing the said bar down upon thefriction-wheel I, which, as it rotates, will act by friction to slidethe bar H back against the stress of thespring f, until the fingerhfalls H. I? is a toothed wheel, to which is attached an eccentric orcam, P 1? is a sliding dog. In the periphery of wheel I is a notch andan incline, 1', whereby the said dog P is caused to move the wheel P onetooth at each revolution of the wheel I.

It is evident that the point of time when the'finger 7). will fall downupon the surface 2 to 3 of the bar H will depend upon the positionoccupied by the notch 4 of the bar H with reference to said finger atthe moment when the end al of lever F passes off from one of the pins '5and rests upon the surface 1 to 2 of bar H; and it is also evident thatthe cam P against which the bar H, when free to move, is forced by thespring f, will determine the position of the said notch 41 withreference to the said finger h.

The operation of this machine is as follows: The clock-work being timedso that the pin 1' will raise the end (1 of the lever F at a given hour,supposed to be that at which it is desired to turn on the gas, the barH, being thereby freed from pressure and relieved from the friction ofthe wheel I, will be thrown forward into contact with the cam P and thesaid finger h will then rest upon the surface 1 to 2 of said lever, andthe pin d will, by said movement, pass off from the projection d intothe slot 61 and, pressing against the incline d, will press down thefinger h upon the bar H into contact with the friction-wheel I. The saidfriction-wheel, continuing its movements with the wheel 0, will slowlyforce the said bar back against the stress of the spring f until it isstopped against the pin 0 ,111 the course of which movement the finger hwill pass oil from the surface 1 to 2, and drop down upon the surface 2to 3, thus permitting the pin d to pass through the slot 0?, therebyleaving the wheel D to make one revolution and give one-half of onerevolution to the wheel E, whereby the crank e forces the rod e eitherup or down, as the case may be. The said rod 6 is intended to beconnected to the cock of the gas-burner, so that such movement of therod shall turn on the gas and set off a friction or percussion match tolight the same. The wheel 0 is provided dog I, it is evident that, bythe said cam P the moment when the gas shall be turned on or off will beautomatically changed each day later or earlier, as the case may be, soas to make the time of such turning on or off the gas conform to thevarying lengths of days in the year.

B is an air-cylinder, through which the rod 6 runs. There is apiston-head on the rod within the cylinder, working closely therein, andsmall apertures are made at each end of the cylinder, or through thepiston-head, for the passage of air. This device is intended to regulateor moderate the movement of the rod 6 which might otherwise be toorapid. The rate of such movement may be regulated by enlarging ordiminishing the apertures in the ends of the cylinder or that in thepiston-head. It is intended that this apparatus, for street purposes,shall be inclosed in a suitable case or box, which is to be attached toa lamppost, and the rod 0 extends therefrom to the gas-burner.

.Whatwe claim, and'desire to secure by Letters Patent, is-

1. The combination of the lever F, provided with the projections 01 andd, the bar H, the wheel D, provided with the pin 1 and the wheel 0,provided with the pins 2' i, one or both driven by a clock-movement,together with pinion (1', wheel E, crank 0 and rod 6 all constructed tooperate as and for the purpose described.

2. The combination of the bar H, spring f, cam P toothed wheel P, dog Pnotched wheel I, all constructed to operate as and for the purposedescribed. I

3. The combination, with the train of wheels D d E, crank 0 and rod 0provided with a piston-head, of the air-cylinder R, the pistonli'eadworking within the cylinder, and the cylinder or piston-head beingprovided with air-apertures, as and for the purpose described.
